That link is for "W5W" & the original link in the 1st post was for "W9W"; Oddjob is asking if there is a difference between the two. Perhaps the "W9W" was a typo, as I too can only find "W5W" now.
Also, Hapa88, is there a difference in color in the 6WLED bulbs you had & the new 25-LED bulbs? {ie. are both crystal-white w/ slight UV-like halo?}
